Additively manufactured milling tool with integrated cooling channels for machining saw profiles

Abstract

Milling tool for machining saw profiles, manufactured by additive manufacturing, with at least one cooling channel integrated in the tool body, which directs the coolant specifically to the cutting edge(s).

Description

Technical field:

[0001] The invention relates to a milling tool for machining workpieces, in particular for the precise machining of saw profiles. It specifically relates to the manufacture and design of milling tools with improved coolant supply. State of the art:

[0002] Milling tools for machining saw profiles are generally made of metal and often have conventional coolant supply systems that either act on the tool from the outside or have simple coolant supply holes. The limited coolant supply frequently leads to insufficient cooling, increased wear, and reduced machining quality. Purpose of the invention:

[0003] The aim of the invention is to provide a milling tool that ensures improved cooling during machining through optimized coolant supply, thereby increasing tool life and improving machining quality. Solution to the problem:

[0004] The milling tool according to the invention is manufactured using additive manufacturing (e.g., 3D printing from metal) and has integrated, complexly designed cooling channels inside the tool. These cooling channels are arranged so that the coolant is directed precisely to the critical areas of the saw profile machining process. Additive manufacturing allows the cooling channels to be realized in a geometrically optimized shape that is not possible with conventional manufacturing methods. Advantages: • Improved cooling of the cutting edges and therefore reduced tool wear • Increased tool life • Optimized processing quality of the saw profiles through constant temperature control • Ability to produce complex cooling channel geometries that are not conventionally feasible • Reduced coolant consumption through targeted supply • Enabling tool designs with complex internal structures through additive manufacturing Example embodiment:

[0005] The milling tool is made of a suitable metallic material, manufactured using an additive process. Integrated cooling channels run within the tool body and terminate near the cutting edges. These channels are partially branched and equipped with inlets and outlets to ensure efficient coolant circulation.
